A chemical kinetic perspective on the low-temperature oxidation of propane/propene mixtures through experiments and kinetic analyses

Our understanding of fuel oxidation has improved with rigorous experimental and theoretical investigations being performed in recent years. As investigation methods evolve, our fundamental chemistry advances. This process allows us to revisit improve existing chemical kinetic models. Propane propene have been studied various facilities at different conditions; however, the interaction these two species not explored well. These play a crucial role larger hydrocarbons constitute significant fraction liquefied petroleum gas. The current study involves an ignition delay time measurements for neat propane/propene (50%/50%) mixtures rapid compression machine range pressures (20–80 bar). auto-ignition experiments are complemented by measurement stable intermediate mole profiles 750 K non-diluted stoichiometric condition 40 bar 50 bar. output from this contributed development NUIGMech1.0 high-pressure conditions that relevant engine applications. is utilized analysis, its performance also compared other mechanisms. analysis used understand controlling provide updates mechanism. Additionally, critical reaction pathways sensitive reactions lead control reactivity explained detail. It found cross-reactions both propane sub-mechanisms mixtures. captures speciation data components shows good predictions studied.
